Rainbow Deep Q-Learning with Kinematics-Aware Design for Cooperative Delta and 3-RRS Parallel Robot Insertion
Hassen Nigatu, Gaokun Shi, Jituo Li +2
This paper presents a kinematics-aware deep reinforcement learning framework based on Rainbow Deep Q-Networks (DQN) for cooperative peg-in-hole manipulation by a Delta parallel rob…
Quantum Machine Learning and Grover's Algorithm for Quantum Optimization of Robotic Manipulators
Hassen Nigatu, Shi Gaokun, Li Jituo +3
Optimizing high-degree of freedom robotic manipulators requires searching complex, high-dimensional configuration spaces, a task that is computationally challenging for classical m…
The Stiffness of 3-PRS PM Across Parasitic and Orientational Workspace
Hassen Nigatu, Li Jihao, Keqi Zhu +4
This study investigates the stiffness characteristics of the Sprint Z3 head, also known as 3-PRS Parallel Kinematics Machines, which are among the most extensively researched and v…
Comparing Z3 and A3 PKM Heads: Which Is Superior and Why?
Hassen Nigatu
